Question

WPF ListView控件允许通过拖放重新排序列。有没有办法禁用它？

我希望一些WPF大师可以帮助我。：）

Answer 1

<ListView.View>
     <GridView AllowsColumnReorder="False">
      ......headers here........
     </GridView>
 </ListView.View>

试试这个

我正在使用带有N个列的WPF listView，其中第1列必须像边距列一样，并且它应始终保持为第1列

如何仅禁用第1列的重新订购，并将其他列“重新排序”？

我可以使用IsHitTestVisible属性禁用第一列的拖放，这将禁用鼠标输入，但我注意到用户可以拖动第二列（例如）并将其放在第一列之前，这将交换第一列和第二列？

我想出了如何做到这一点：

1）首先订阅活动：

GridView gridView = this.dbListView.View as GridView;
gridView.Columns.CollectionChanged += new NotifyCollectionChangedEventHandler(Columns_CollectionChanged);

2）事件处理程序是：

    /// <summary>
    /// This event is executed when the header of the list view is changed - 
    /// we need to keep the first element in it's position all the time, so whenever user drags any columns and drops
    /// it right before the 1st column, we return it to it's original location
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    void Columns_CollectionChanged(object sender, NotifyCollectionChangedEventArgs e)
    {
        GridViewColumnCollection collection = (GridViewColumnCollection)sender;
        if (e.Action == NotifyCollectionChangedAction.Move) //re-order event
        {
            if (e.NewStartingIndex == 0) //if any of the columns were dragged rigth before the 1st column
            {
                this.Dispatcher.BeginInvoke((Action)delegate
                {
                    GridView gridView = this.dbListView.View as GridView;
                    //removing the event to ensure the handler will not be called in an infinite loop
                    gridView.Columns.CollectionChanged -= new NotifyCollectionChangedEventHandler(Columns_CollectionChanged);
                    //reverse the re-order move (i.e. rolling back this even)
                    collection.Move(e.NewStartingIndex, e.OldStartingIndex);
                    //re-setup the event to ensure the handler will be called second time
                    gridView.Columns.CollectionChanged += new NotifyCollectionChangedEventHandler(Columns_CollectionChanged);
                });
            }
        }

    }
